Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell manufacturing, and in particular relates to a coating vacuum drying furnace production line. Background Art

[0002] During the processing of battery cells, it is necessary to coat the surface of the battery cells with liquid medicine and then send them to a vacuum drying furnace for drying. Moreover, after each drying, it is necessary to enter a clean room environment to maintain the cleanliness of the battery cells. Currently, the complete perovskite battery cell process requires multiple layers of coating to meet the process requirements. Existing coating machines can generally only coat one layer of liquid medicine. If the battery cells need to be coated with multiple layers of liquid medicine, multiple coating machines are required, which leads to an increase in the cost of the coating machines. When the battery cells coated with the coating liquid are sent to the vacuum drying furnace, the long route leads to low transportation efficiency of the battery cells, which increases the transportation time. Since there is no external protective device during the transportation of the battery cells to the vacuum drying furnace, the battery cells are easily exposed to the air, causing contamination of the battery cells, resulting in a significant reduction in the processing quality of the battery cells. Since the complete production of perovskite battery cells requires a variety of coating devices with different processes, no matter which coating device is used, it needs to be sent to the vacuum drying furnace. The existing linear conveyor line is inefficient and cannot meet the requirements.

[0003] Therefore, it is necessary to provide a coating vacuum drying furnace production line that has high conveying efficiency, reduces the number of coaters and avoids battery contamination. Utility Model Content
